**Front Cover Description for Jiu Jitsu-Themed Birthday Card:**

**Background:**

- The background is a clean, flat, light teal to give a fresh, modern look. Use a subtle geometric pattern of circles and triangles in slightly darker teal tones to add depth and texture without overwhelming the scene.

**Central Scene:**

- In the foreground, depict a large, stylized birthday cake shaped like a dojo mat. The mat is a rectangular flat object with a red and white color scheme, using crisp lines to highlight the jiu jitsu theme. The edges are rounded to soften the appearance.

**Birthday Cake Elements:**

- Place a set of jiu jitsu belts in varying colors (white, blue, purple, brown, black) neatly stacked and curled around the base of the cake. These belts are vector-style with a flat design and clear outlines, with realistic knot detailing.

- On top of the cake, illustrate a pair of grappling figures made from simple shapes. The figures are abstract, using flat circles for heads and rectangle limbs, reminiscent of Malika Favre's minimalistic style. They appear as if mid-throw, with one figure flipping the other.

**Decorative Elements:**

- Around the cake, scatter vector confetti in a dynamic swirl, using a color palette of bright primary colors like red, blue, and yellow, mixed with some black and white stripes to add visual interest.

- Include a few flat, vector-style birthday candles atop the cake, each shaped like a martial arts belt in different colors, with crisp lines and sharp edges for the flames.

**Typography:**

- At the top, in bold, crisp sans-serif typography, write "Happy Birthday!" in black with a slight shadow to make it pop. Use a touch of the Patrick Seymour-style linear shading on the text for a 3D effect.

- Below the main text, add the subtitle "Roll into another year of awesomeness!" in smaller, simple font, aligned to the right to create a balanced composition.

This greeting card cover should embody a humorous and celebratory vibe, with a clear jiu jitsu influence, presented in a modern, flat vector style.
